When the stream is deleted while the redis stream source is running, the service should recreate the stream and the group

[tdeverdiere]

Problem
When the stream is deleted, while the redis stream source is running, the service does not recreate the stream and the group so it stays in error logging :
"GROUP sync is missing and creates error : NOGROUP No such key 'my_stream' or consumer group 'a_group' in XREADGROUP with GROUP option"

To fix this, i would capture the error and send a Redis command to recreate the group. But i did not look much at the code.

Persona:
Event consumer (developer)
System Operator

Exit Criteria
No more error logs written like described above when the Redis stream is deleted

Time Estimate (optional):
1 day ?

Additional context (optional)
Restarting the service fixes the problem, so it is a workaround now.
